If you have Cubase 9 you have Halion Sonic (or SE); more versatile than Forte 1.6 (GM only, last updated in 2007), with it's GM2. HS sounds IMO also better. For BIAB use you need jBridge to create the 32 'shell". In my case it all installed automatically. With Halion Sonic open: go to OPTIONS, and set it to GM mode, BIAB remembers the GM settings ever after you make here.

shell2vst.exe BTW is a Waves tool to do with unpacking their VST3 waveshells to separate files; i think waves works with DXi protocols which automatically runs as VST in Steinberg stuff.

PS FXexpansion used to have a DX to VST wrapper, but it seems to be non available today. -F
